There were two of you, in both teams, standing on the flag in an otherwise empty server so that the round wouldn't end and you wouldn't have to look at the game even to respawn. I don't know how long you were at it, but there was more than 15 minutes between it being reported on IRC and me logging on to find you still there, so I'll wager it was a while.
You were leeching, and you've been banned for it before. No use in making excuses.
I guess admins are simply banning everybody standing still for 10 seconds..
For this insightful comment, I award you a warning. Don't post if you haven't got anything to say.
